现在有很多相机类型，有的鱼眼相机照完的图片会发生畸变，为此，我们要进行鱼眼图片校正。本程序正是针对鱼眼图象的校正程序，里面有详细的注释说明相信只要是有一定的基础的人都能看懂。不过，还有差值部分没做完哪，有待完善。(Now have a lot of camera types, and some fish-eye camera images will be finished according to distortion, to that end, we have to carry out fish-eye image correction. This procedure is for fish-eye image correction program, which has detailed notes as long as it is believed that the basis of a certain person can understand. However, there is some difference which did not finish, remain to be improved.)

页式虚拟存储器的页面置换算法一般有： 最佳置换算法（OPT），先进先出置换算法（FIFO），最近最久未使用置换算法（LRU），Clock置换算法，最少使用置换算法（LFU），页面缓存算法（PBA）等。 先进先出（FIFO）置换算法是最直观的置换算法，由于它可能是性能最差的算法，故实际应用极少。在这里我只使用前面三种算法来进行页面调度(Page replacement algorithms for page virtual memory generally include the best permutation algorithm (OPT), advanced first out permutation (FIFO), the most recent unused replacement algorithm (LRU), Clock permutation algorithm, minimum use of permutation (LFU), and page caching algorithm (PBA). The first in first out (FIFO) replacement algorithm is the most intuitive replacement algorithm, because it may be the worst performing algorithm, so there are few practical applications. Here I only use the first three algorithms for page scheduling.)

银行家算法模拟程序的实现 用可视（图形）化界面完成银行家算法的模拟程序。 模拟程序能够实现对不同数目进程，不同数目资源种类，不同当前状态的测试，通过银行家算法判断任意次数的资源请求是否会得意满足，并对提出资源请求的进程作出正确处理。 模拟程序还需要能够正确回收资源，并在回收资源后判断是否需要唤醒阻塞进程，如需要则将先前因申请资源失败而被阻塞的进程唤醒，并提供资源分配(Bankers algorithm simulation program realization )
